Given numbers are 425, 255, 111, 787
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(425, 255) = 1275
GCD(425, 255) = ( 425 x 255 ) / 1275
= 425 / 255
= 425
Step2:
LCM(85, 111) = 9435
GCD(85, 111) = ( 85 x 111 ) / 9435
= 85 / 111
= 85
Step3:
LCM(1, 787) = 787
GCD(1, 787) = ( 1 x 787 ) / 787
= 1 / 787
= 1
So, Greatest Common Divisor of 425, 255, 111, 787 is 1
